Defined in header <mutex>
template< class Mutex > class unique_lock;		(since C++11)

The class unique_lock implements general-purpose mutex ownership wrapper allowing deferred locking, timed locking, recursive locking, transfer of lock ownership, and use with condition variables. The class is non-copyable but movable.

[edit] Member types

Type	Definition
mutex_type	Mutex

[edit] Member functions

(constructor)	constructs a lock, optionally locking the supplied mutex (public member function)
(destructor)	unlocks the associated mutex, if owned (public member function)
operator=	unlocks the mutex, if owned, and acquires ownership of another (public member function)
Locking
lock	locks the associated mutex (public member function)
try_lock	tries to lock the associated mutex, returns if the mutex is not available (public member function)
try_lock_for	attempts to lock the associated TimedLockable mutex, returns if the mutex has been unavailable for the specified time duration (public member function)
try_lock_until	tries to lock the associated TimedLockable mutex, returns if the mutex has been unavailable until specified time point has been reached (public member function)
unlock	unlocks the associated mutex (public member function)
Modifiers
swap	swaps state with another std::unique_lock (public member function)
release	disassociates the associated mutex without unlocking it (public member function)
Observers
mutex	returns a pointer to the associated mutex (public member function)
owns_lock	tests whether the lock owns its associated mutex (public member function)
operator bool	tests whether the lock owns its associated mutex (public member function)

[edit] Non-member functions

std::swap(std::unique_lock)	Specialization of std::swap for unique_locks (function template)
